Claims (3)

  1. Siège de montage (1) pour machines-outils permettant un accouplement coaxial de la tige (2c) d'un élément porte-outil (2), caractérisé en ce qu'il comprend intérieurement un manchon cylindrique (3) supportant plusieurs roulements à billes (4i) disposés sans jeu entre la surface intérieure (1i) du siège de montage (1) proprement dit et la surface extérieure (2e) de ladite tige (2c), ledit manchon (3) étant apte à effectuer un mouvement de coulissement axial (S) en direction de l'extérieur du siège de montage (1) sur une longueur inférieure ou égale à la longueur axiale (LH) de sa zone occupée par lesdits roulements à billes (4i), sa course axiale au-delà étant arrêtée par les moyens formant butée de fin de course (3s, 1r), et ledit manchon (3) comportant, montés sur lui, des moyens aptes à empêcher une séparation des roulements à billes (4n) lorsque sa zone occupée par ces derniers est située à l'extérieur du siège de montage (1).
  2. Siège de montage selon la revendication 1, dans lequel lesdits moyens formant butée de fin de course consistent en une partie saillante (3s) du manchon (3), qui, à la fin dudit mouvement de coulissement axial (S), appuie contre un épaulement de contact profilé (1r) formé sur ladite surface intérieure (1i) du siège de montage (1) proprement dit.
  3. Siège de montage selon l'une quelconque des revendications précédentes, dans lequel ledit manchon (3) comporte plusieurs cavités (3n) capables de loger en elles un nombre correspondant de roulements à billes (4n) faisant saillie des deux côtés (3a, 3b) du manchon (3) proprement dit, ce dernier comportant, montée sur lui, coaxialement sur sa face extérieure, une cage en tôle métallique cylindrique (5) dans laquelle sont formés plusieurs trous (5n) conçus pour permettre auxdits roulements à billes (4i) de tourner et de faire saillie extérieurement à travers eux sans pouvoir sortir desdits trous.
